TYPE-WRITING MACHINE? Patented Sept. 15, 1914.

Application filed May 7, 1913. Serial No. 766,026.

i To all whom it may concern Be it known'that I, HERBERT H. STEELE, citizen of the'United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- W'riting Machines, of which the following I is :a specification.

My. invention relates chiefly to typewrit-' ing machines, though it is also applicable to other sorts-of machines and it has for its principal object to provide a simple, convenient and eflicient means for numbering lines of writing produced by typewriters,

- adding machines or other printing ma- I parts, all of which will be fully set forth herein and particularly pointed out in the claims. I

The specific embodiment of my invention illustrated in the drawings, consists of a, device for numbering the lines of writing on sheets of paper by a Monarch typewriter. In this typewriter the ,paper is fed through the machine from one .line space position to another. In some other sorts of typewriters the printing mechanism is fed from one line space positlonto another along the paper. In either event my devicewould be mounted on the paper feedv elemeht that did not hold the paper. y

In the accompanying drawings, all of which are on an enlarged scale, Figure 1 is a fragmentar front-to-rear vertical sectional view 0 enough of a Monarch typewritercarriage to illustrate the application of my invention thereto, my line numbering device being shown in side elevation. Fig. 2 is a front torear vertical sectional view through said line numbering device about on the line axem of Fig. 5. Fig. 3 is a diagram to illustrate the principle of the gear ing which controls the number wheels. Fig. 4: 1s a front view of the line numbering attachment and a'few associated parts. Fig. 5") is an axial sectional view of the numberlng mechanism. Fig. 6 is a view of one of the number wheels. Fig. 7 is a view to illustrate the relative positions in which the several numbers are printed.

The Monarch typewriter carriage comprises a transverse back bar or main bar 1 from which two brackets 2 project toward the front of the machine, one bracket at each end of the bar. Said brackets have journaled therein .the shaft -3 of a roller platen 4 with which platen cooperate certain paper feed devices, most of which are not shown in the drawings, but which comprise feed rollers, apaper apronor deflector and other devices well knownin the art. These may be saidv to include a platen scale plate 5,-which is mounted on certain arms not shown, so as to stand in the relation to the platen illustrated in Fig. 1. The paper feed mechanism or paper controlling machanism also includes certain :paper fingers and associated devices, -mounted on a rod 6, which rod extends from one of the brackets' 2 to the other above the platen. Said bar 6 is connectedto brackets 7 that extend upward from the'brackets 2, and said rod has its ends bearing against the inner faces of said brackets 7 to each of which the rod is secured by means of a screwv 8 passing through the bracket and threaded into the end ofthe rod. This rod also is usually formed across each end with a rib or spline that fits in a suitable groove in the bracket 7 so as to lock the'rod 6'against turning; Said rod is, however, detachable from the carriage by removing the screws 8, and when said rod-is detached ny numbering device and the ordinary left hand paper finger device, are readily interchangeable by slipping over .the end of the rod.

The feeding of the paper from "one line space position to another, is effected in the Monarch machine by means including a line space handle 10 projccting upward from the forward end of a rocking'member 11, which is controlled by a restoring sprin 12. When the handle 10 is pushed towar the right, the shaft or member 11 is rocked and a line space pawl 13 is suitably operated against a ratchet wheel, not shown, which results in the turning of the platen a suitable distance to space between lines. The distance through which the platen is turned at each operation of the handle 10, can be varied by means of a device 14: which need not be here specifically described but which is well known in the art. In the Monarch machine this device is capable of setting the apparatus to space a single ratchet tooth distance or a distance of either two'or three ratchet teeth, as desired. The great bulk of typewriting is done with a spacing equal to two ratchet teeth or what is commonly called double spacing, and my attachment is, in the specific instanceillustrated in the drawings, adapted to number correctly thelines of writing thus double spaced. It will, of course, be understood that nothing more will be required than a change in the dimensions of parts to adapt the mechanism for other spacings.

My line numbering device comprises a support 15 mounted on and adjustable along the paper finger rod 6 of the typewriter. This support consists of an. arm which, except for its adjustability lengthwise of the rod 6, is rigid and is rigidly mounted on said rod from which it extends first upward and thence toward the front of the machine, being similar in many respects to, and, except as to its forward end, it may be identical with, the corresponding part of the paper finger device ordinarily employed on the Monarch typewriter. The rod 6 is formed on its under side with a longitudinal groove 16 in which is adapted to slide a spline 17 which, in the present instance, is substantially identical with the corresponding part connected with the Monarch paper finger arm. This spline by its elasticity makes a frictional resistance to any motion of the support 15 lengthwise of the rod 6 but permits said support to he slid along said rod by the application of a little force; and said spline also prevents turning of said support about said rod. In short, the support 15 is mounted on and adjustable along the rod 6 in a manner substantially identical with the support of the ordinary Monarch paper finger device and, as will presently appear, my line numbering device is, in ad dition to its numbering function, adapted to perform also the functions of the said Monarch paper finger device. 7 a

A block or frame 18 has two parallel, rearwardly directed arms 20 which embrace the forward end of the support 15, to which said arms are pivoted by means of a pivot pin or shaft 21. Said block or frame has also two forwardl directed arms 22 offset toward the right from the parallel arms 20 and connected at the back by a sort of yoke bar 23, Fig. 2. The numbering mechanismis mounted in these arms 22, being supported for the most part on a fixed axle 2 1,

Fig. 5, which is inserted between the two arms 22 to which it is secured atone end by a screw 25, andat the other end by a screw 26, said screws passing through the respective arms 22 and threaded into the ends .75

from the latter toward the left, as shown in Fig. 5.

The left-hand face of the wheel 27 is chambered out to form a circular depression 32,

Fig. 6, in which lies a tens printing wheel or,

ring 33, the chamber 32 being so located that the ring 33 lies at the left-hand side of the type 31 on the wheel 27. Said ring is internally toothed so as to constitute a gear wheel that meshes with an elongated pinion 34 rigidly secured on or made integral with the axle 2 1. A second internally toothed tens printing ring 35 also meshes with the pinion 34 at the left of the wheel 33, and said wheel 35 lies at its periphery just at the left of the type 30 on the wheel 27. A member 36 is journaled on the axle 2 -at the left of the wheels 33 and 35, said member itself constituting a wheel which is chambered out on its right-hand face similarly to the wheel 27 but oppositely, the wheel 35 lying in such chamber and being diametrically opposed to the wheel 33 when considered with relation to the axle 2t. The two wheels 27 and 36 are connected to-rotate together by dowels 37, Fig. 2, that engage holes 38, Fig. 6. By means of these dowels the two wheels 27 and 36 are connected so as to act practically as a single wheel. It will be perceived that if this compound wheel be caused to rotate about the axle 24 the wheels 33 and 35 will revolve about said axle and about the pinion 34 after the fashion of internal planetary gears. The walls of the chambers 32 will cause them to revolve about the axle and their engagement with the fixed pinion 34 gill cause them to rotate within said chamers.

' In order to rotate the wheels 27 and'36' a wheel 40 is (iournaled on the hub 28 of the not rigidly connected with the wheel 27 but is connected with said wheel by means of a pin 42, Fig.1, pro'ecting from the wheel 27 into an arc-shape slot 43 in the wheel 40,

so that the two wheels 40 and 27 .are constrained to turn together except that one can have an amount of lost motion with respect to the other, measured by the length of the slot 43. In order normally to restore'such lost position a second pin 44 projects from the wheel 27 into a longer arc-shaped slot 45 in the left-handface of the wheel and a coiled spring 46 is compressed between said pin 44 and one end of said slot 45, the construction being such as tohold the several parts normally in the relative positions shown in Fig. 1. p

The frame 18 is acted upon by a leafspring 47 secured to the upper surface of the arm 15 and the tension of which can be regulated by an adjusting screw 48 threaded into the said arm. The forward end of the spring 47 is-so shaped and positioned as thatit can engage the cross bar 50, Fig. 4, that connects thetwo arms 20, either on top of said bar, as shown in said Fig. 4, or in front of said bar, depending upon the position of said frame '18. When the parts are in the position shown in Figs. 1 and 4,

the spring 47 presses the frame 18 downward and presses the wheel 40, 41 against the platen; but if the frame 18 be raised as by the handle 26 until the spring 47 catches over the front edge of thebar 50, then said spring will yieldingly hold the frame in its elevated position out of contact with the platen.

In order to determine a normal position of the compound wheel 27, 36, any suitable form of indicating device can beprovided, such device preferably consisting of a yielding detent. As here shown, especially in Fig. 5, a ball 51 is mounted in a cylindrical cap 52 which is threaded into the left-hand one of the arms 22 and said ball is pressed toward the right by a spring 53 compressed between the ball and the end of the cap. A suitable depression is formed in the lefthand face of the wheel 36 so that the wheels can be turned to normal position by hand until the depression is engaged by the ball when the wheels will be held in that posi tion yieldingly.

- An endless inkribbon 54, Fig. 4, is conducted around the printing wheels by ay curved guide 55 and said ribbon also runs the end of the shaft. The wheel 33 has onit four types 57, 58, 59 and 60; these types are adapted to print respectively 0 1, 2 and 3 7 as will be best understood by reference to Figs. 2 and 3. The wheel 35 also contains four types 61, 62, 63 and 64 .ada ted respectively to print the numerals When the numbering device is not in use it will stand in a position Where the printing wheels are out of contact with the platen, and in this position of the parts the spring 46 will cause the Wheel 40 to assume the position with respect to the wheel 27 indicatcd in Fig. 1. When a piece of paper is put into the machine to be written upon, it is first brought to the position for Writing the first line on said piece of paper; afterward. the numbering device is depressed by means of the handle 26 until the wheel 41 is pressed against the paper by the spring 47. In the Monarch machine the printing is on the front face of the platen, horizontally in front of the axis of the shaft 3, and it will be perceived from an inspec- 'tion of Fig. 1 that my numbering wheels engage the platen a little distance above the writing line. It will also be perceived by an inspection of Figs. 2 and 3, that in the initial position of the parts no one of the types is in position to print. When the numbering device is moved down to its position shown in Fig. 1, and the writing upon the paper is proceeded with, the paper will be line spaced from time to time by means of the handle 10 and its connected devices. As the platen turns the wheel 40 will be turned by it until the rear end of the slot 43 reaches the pin 42 when the Wheel 27 will be forced to turn with the wheel 40 and the ball v 51 will be forced outof its socket in the Wheel 36, after which the wheels 40, 27 and 36 will all rotate together, the'friction due to the pressure of said ball 51 and to other causes, preventing the spring 46 from turning the numbering wheels. A certain amount of such rotation will bring the type 31 to position to print on the paper that is passing beneath the type wheels. The depression for the ball 51 is so located and the slot 43 is so proportioned that the type 31 will reach the printing position at the same time that the fifth written line reaches the position correspond- Said guide '55 is ing to the point of tangency between the platen and the numbering wheels so that the 5 will be printed on the paper. As shown in Fig. 3. the type 57 on the wheel 33 initially stands a little in advance of the type 31 on the wheel '27. The wheel 33, however,

'mounted on the arm 15 after the ordinary fashion of this part of the Monarch typenot only revolves around the axle 24: but also has a retrograde rotation due to its engagement with the pinion 34: and this is such that by the time the type 31 reaches printing position the type 57 will be directly in line with said type 31 and the figures 05 will be printed in the position indicated at a, Fig. 7 the 0 being printed by the type 57 and the 5" by the type 31.

The wheel 40 is of such circumference that it receives a complete rotation for each ten lines of writing, and, therefore, by the time the tenth printed line reaches the point of tangency between the platen and the numbering devices the type 30 will be in printing position, and the type 61 is so positioned on type 30 is in printing position said type 61 will be in line with said type 30 and just at the left of it so that the number 10 would be printed as shown in Fig. 7 at b, the 1 being printed by the type 61 and the 0 by the type 30. At the end of the next five letter space operations the type 31 will again be at printing position and by this time the type 58 will have so far retrograded by rotation of the wheel 35 that it will be by the side of the type 31 and the number 15 will be printed as shown in Fig. 7 at 0. The next printing will be the number 20 shown in Fig. 7 at d, the 2 being printed by the type 62 and the 0 by the type 30. The number 25 as shown at e, in Fig.7, will be printed by the type 59 and the type 31 and so on as far as the writing extends. The units of the numbers, namely the and 5 are printed by thewheel 27 and the tens by the planetary wheels. The column of numbers is staggered down the page as shown in Fig. 7, because some of the tens are printed by the wheel 33 and the alternate tens by the wheel 35.

lVhen a page of writing is complete and drawn out of the machine the wheel 40 will continually turn with the paper as long as said paper runs under it. At the end of the numbering operation the operator lifts the frame 18 so as to bring the several wheels out of contact with the platen, at which time the spring 46 will immediately bring the wheel 40 back to the relative position shown in Fig. 1. The operator then by hand turns the wheel 27 36 until the printing wheels are restored to normal position ready for the writing of another sheet of paper.

The gearing shown in-the present instance is such that each of the wheels 33, 35 will re- 'ceive a complete rotation upon four complete rotations of the wheel 27, 36. In the present instance the pinion 34 is shown with ten teeth and each of the wheels 33 and 35 with forty teeth.

A paper finger or guide plate 65 is writer. The upper part of said plate 65 is secured-to a sheet metal device 66 so folded as to have two branches that embrace the arm 15 to which they are pivoted at 67 and a spring 68 presses the parts downward ,to press the paper finger against theplaten. This paper finger or guide plate can, of

course, be formed in various ways as far as my invention is concerned, but as here shown it IS made wider than usual and is formed ;with an opening 70, Fig. 1, through which :the various printing wheels and the ink ribbon can project in order to make contact with the platen or the paper.

the wheel 35 that at the same time that the It will be perc'eived that the mechanism which has been described is adapted to perform all of the functions of the ordinary paper finger and marginal feed roller devices, the wheel 40, 41 takin the place of the1 ordinary small margina? paper feed rol er.

In Fig. 1 I have shown in dotted lines a I ion of the types on the type block 72, it is necessary that said types be formed with a concave face to conform to the convex curvature of the platen. My numbering device does not print by this sort of impact but prints by a rolling action. The faces of my 3 types are therefore convex, partaking merely or substantially of the general cylindrical form of the wheels which carry them. It is much easier to make a number of types of this character on a single type carrier and to have them all work properly than to make a number of concave types adapted for printing by impact.

Various changes can be made in the details of construction and arrangement without departing from my invention.
